Purpose: The aim of this study was to introduce the phenomenon that stenosis or occlusion occurs less frequently in the innominate artery than in the right subclavian and common carotid arteries, which are not first-order branches of the aorta, in Takayasu arteritis (TA).Materials and Methods: We retrospectively reviewed the medical records and image findings of all patients who were diagnosed with TA from 2006 to 2014. Two vascular surgeons and two radiologists interpreted the images by disease character, location, and extent of occlusion based on computed tomography angiography, magnetic resonance angiography, or digital subtraction arteriography. We have also reviewed the literature on arterial involvement in TA. Results: A total of 42 patients were diagnosed with TA. The mean age was 43.9 years, and 83.3% (35/42) of the patients were women. The left subclavian artery was the most common stenosis or occlusion site (17, 40.5%) among the aortic branches. The innominate artery was a less common site (3, 7.1%) than the right subclavian artery (4, 9.5%) and the right common carotid artery (9, 21.4%). All innominate artery cases were found after endovascular procedures of the right subclavian or common carotid arteries.Conclusion: The innominate artery might develop stenosis or occlusion less frequently than the right subclavian and common carotid arteries in Korean TA patients.

Previous Satisfaction and Positive Word-of-Mouth Communication as Antecedents to Purchase Intention in Transmedia Storytelling

박봉원,안재현 한국콘텐츠학회 2010 International Journal of Contents Vol.6 No.4

As the reuse of content becomes a strategy for the entertainment industry, managerial insight on customers is needed to be cultivated in order to run a successful business. This study analyzes the impact of previous satisfaction on consumption intention for content in another medium. To do this, two data sets are collected: cases of movie-to-TV series and TV series-to-movie and analyze them using a structural equation modeling approach. The results of our analysis show that satisfied viewers of a movie tend to communicate their positive feelings via word-of-mouth communication and demonstrate repurchase intention of another medium afterward. However, satisfaction does not automatically lead to repurchase intention in another medium. While satisfied viewers of a TV series show a statistically positive repurchase intention for a movie, satisfied viewers of a movie do not show a direct repurchase intention for a TV series. This result demonstrates an asymmetric relationship between satisfaction and repurchase intention across media, and its strategic implications are further discussed.

잠재고객의 OSMU(One Source Multi Use) 콘텐츠 수용에 대한 탐색적 분석

박봉원(Bong-Won Park),이건창(Kun Chang Lee) 한국경영과학회 2010 經營 科學 Vol.27 No.2

There is an increasing interest in contents such as movie, drama and game using transmedia storytelling. It includes Le Grand Chef, The War of Flower, Dae Jang Geum, The Matrix, Harry Potter and The Lord of the Rings. However, transmedia contents have not always been successful. To study the factors affecting possible outcomes of transmedia storytelling, we analyzed the intention on transmedia of potential consumers who have not been exposed to transmedia contents before. To this end, we investigated two different cases : first, potential customer intention to watch dramas which will be produced after launching comic-based movies; second, potential customer intention to see movies which will be made after broadcasting comic-based TV dramas. In each case, we analyzed the outcomes from potential customers by applying several variables including gender, exposure to the original and components of contents (plot, quality of act and music etc). Our study showed that potential customers prefer movies or TV dramas with quality of acting, directing, casting and storylines. Interestingly, the quality of acting is more important in dramas than in movies and casting is an appealing factor to potential customers in movies. In TV drama cases, potential customers have high watching intentions when they read the original content. Among them, male potential customer have low watching intentions on TV drama when they did not read the original content. However, female potential customers have high watching intentions on TV drama regardless of the previous exposure to the originals. In movie cases, female potential customers have higher intentions on seeing movies than male. These results suggest that one needs to consider several factors such as casting, acting and gender for generating transmedia contents with a high probability of success.

인터넷의 웹페이지는 다양한 형태로 존재하지만, 크게 텍스트 중심의 웹페이지, 텍스트와 이미지로 구성된 웹페이지, 그리고 텍스트와 동영상으로 구성된 웹페이지로 구분할 수 있다. 본 연구에서는 콘텐츠 제작방식에 따라서 변하는 소비자들의 지각된 위험 수준과 미디어 풍부성이 미치는 영향을 분석하며, 이들 요인이 고객만족에 미치는 영향을 분석한다. 분석결과, 텍스트 형식의 웹페이지가 텍스트와 이미지 혹은 동영상으로 구성된 웹페이지에 비해서 지각된 위험 중 성능위험, 심리적 위험, 시간 위험 등으로 구성된 개인적 위험을 더 크게 느끼는 것으로 나타났다. 또한, 미디어 풍부성 측면에서는 텍스트와 이미지 혹은 동영상으로 구성된 웹페이지가 텍스트 위주의 웹페이지에 비해서 상징성 및 사회적 실재감이 높은 것으로 조사되었다. 그리고 개인적 위험 및 텍스트 형식의 웹페이지는 고객 만족에 음의 영향을 미치며, 상징성 및 사회적 실재감은 양의 효과를 가진다. 본 연구는 지각된 위험과 미디어 풍부성의 개념을 콘텐츠 제작방식과 연결시킴으로써 기대와는 달리 동영상 콘텐츠가 폭발적으로 성장하지 못한 점에 대해서 규명한데 의의를 둔다. Internet web pages can be classified by three major types such as texts only, images with texts and videos with texts. The purpose of this paper is to analyze how customers recognize and respond perspective of perceived risk and media richness with regard to design patterns of internet web pages. Additionally, we will examine the extent to which aforementioned factors affect customer satisfaction. Analyses with perceived risks revealed that customers feel less personal risks including performance, psychology and time/convenience when used web pages of text-images and text-videos, compared to text only based web pages. However, customers feel that web pages consisting of image-text or video-text have higher points in terms of symbolism and social presence in media richness, compared to text only based web pages. Finally, we showed that personal risk and text-based Web page negatively affect but symbolism and social presence positively impact on customer satisfaction. Therefore, this study suggests a clue that why video-based Web content did not grow different from many people's expectation.

조남용,박봉원 한국인터넷전자상거래학회 2017 인터넷전자상거래연구 Vol.17 No.2

Since online game industry keeps growing fast, online game players’ behaviors have become interesting topic for researchers. Prior researches mostly measured attitude, flow, satisfaction, perceived enjoyment and playfulness to describe online games players’ behaviors. Our study investigates psychologically negative factors like perceived loneliness and stress which haven’t been attracted much attention. With positive factors such as character identification and enjoyment, this study revealed perceived stress significantly affects flow which directly affect online game players’ loyalty. In addition, we shed light on methodological approach of Bayesian Network(BN) structuring to describe the relationship between factors. After empirical approach with Structural Equation Model(SEM) to test our hypotheses, we apply various types of BN. Combining partially subsets of BN(CBN) with each other, a better performing whole structure of nodes could be built. Moreover, we conducted structuring a BN based on SEM(SBN). SBN is found to have some advantages of predicting performance and help managerial decision by what-if diagnosis. Other implications of our approaches, limitation, and suggestions for further researches are also discussed at the end of this study.

When new services are introduced, interaction among existing and new services has to be considered. The interaction can be characterized by the substitution or complementary effect among services. This paper analyzes how the interaction among services affects the customers’ subscription decision in telecommunication services industry. Based on a face-to-face in-depth survey from a sample of 1,200 respondents, a new wireless internet access service or WiBro is analyzed to identify the substitution/complementary effect in relation to the existing other telecommunication services. Additionally, the important factors explaining both customers’ subscription and substitution decisions are identified. The analysis results indicate that males and students are more likely to subscribe WiBro service. Interestingly, family size positively affects the subscription decision. However, heavy users of on-line game are reluctant to subscribe WiBro service. Among the potential WiBro subscribers, the customers who are less satisfied with the existing fixed line broadband internet access service are more likely to stop subscribing the fixed line service, which implies substitution by a new service. We believe that the consideration of the interactions among services is essential to devise a winning strategy for the new services in the highly uncertain telecommunications business environment.
